Abstract

The invention relates to the technical field of parking air conditioners, and in particular relates to a method for controlling oil return of a parking air conditioner. The invention aims to solve theproblem that existing parking air conditioners can not guarantee the normal oil return of a compressor. To solve the above problem, the parking air conditioner of the present invention includes a compressor, an indoor radiator, an internal fan, a throttle valve, an outdoor radiator and an external fan. The parking air conditioner is installed in a vehicle. The vehicle is equipped with a storage battery which is connected to the parking air conditioner to supply power to the parking air conditioner. The oil return control method includes steps of detecting the operating frequency f of the compressor in a first detecting period T1; comparing the operating frequency with the magnitude of the first preset frequency f1; and selectively controlling the parking air conditioner to operate a firstforced oil return mode based on the comparison result. Through the above control method, the oil return control method for the parking air conditioner of the present application can realize effectiveoil return during the parking air conditioner operation, and fully lubricate the compressor to ensure the user's use experience.

Description

technical field [0001] The invention relates to the technical field of parking air conditioners, in particular to an oil return control method for parking air conditioners. Background technique [0002] With the development of the transportation industry, the driving environment of large transport trucks has also been greatly improved. Generally, parking air conditioners are installed in transport trucks. Compared with the traditional car air conditioner, the parking air conditioner does not need to rely on the vehicle engine to start, but is directly driven by the vehicle battery, so it can run when the car is turned off, which is a more energy-saving and environmentally friendly air conditioner. [0003] However, the driving conditions of transport trucks are generally relatively bad. When traveling on uphill or rough roads, the car is prone to tilt or bump, and the compressor will also tilt accordingly. If the driver is using the parking air conditioner at this time, then...
